bindfs

Mount directories with altered ownership and permissions via FUSE

TLDR

Mount a directory to another location

$ sudo bindfs /path/to/source /path/to/mount

Mount with user mapping

$ sudo bindfs --map=user1/user2 /path/to/source /path/to/mount

Force all files to appear owned by a specific user and group

$ sudo bindfs --force-user=user --force-group=group /path/to/source /path/to/mount

Mount with modified permissions

$ sudo bindfs --perms=0755 /path/to/source /path/to/mount

Mount as read-only

$ bindfs -o ro /path/to/source /path/to/mount

Unmount

$ sudo umount /path/to/mount

SYNOPSIS

bindfs [OPTIONS] source mountpoint

DESCRIPTION

bindfs mounts a directory to another location with different ownership and permissions. It uses FUSE to create a view of a directory tree with modified permissions.

PARAMETERS

--map= user1/user2

Map ownership from user1 to user2.

--force-user= user

Force all files to appear owned by user.

--force-group= group

Force all files to appear owned by group.

--perms= mode

Set permission bits for all files (octal or symbolic).

--create-as-user

Change owner/group of new files to the caller's uid/gid.

--resolve-symlinks

Resolve symbolic links in the source directory.

--enable-ioctl

Forward ioctl calls to the underlying filesystem.

-r, -o ro

Mount as read-only.

-o options

Pass FUSE mount options.

--multithreaded

Run bindfs in multithreaded mode.

CAVEATS

Changes to ownership mapping are bidirectional - newly created files are mapped back. Requires FUSE support. Use umount to unmount the bindfs filesystem.

HISTORY

bindfs is a FUSE filesystem for mounting directories with altered permissions.
